The second one couldn’t represent a right triangle
(2x-20)/3 = 2x start by multiplying both sides by 3
number of accurate weather forecast over total number of days
21/36 to percentage is 58.33%
hence, 58.33% is the probability that the forecast tomorrow will be accurate.
Answer:
Step-by-step explanation:
you have a right triangle
to find the missing length(x) you will use
a^2+b^2=c^2
where c is the hypotenuse
49^2=25^2+x
x^2=49^2-25^2=2401-625=1776
x=
=42.1
Y=9x-2
3x-2y=7
3x-18x+4=7
-15x=3
x=-1/5
y= -19/5
